PROBLEM TO BE SOLVED: To improve a discharge apparatus by especially taking into consideration to enhancement of a spraying pattern. SOLUTION: The discharge apparatus for the flowing substance has a discharge sleeve (20) provided with a discharge port (22) for discharging the substance on its one end; and a closure pin (30) provided in the discharge sleeve (20). The closure pin is relatively movable in a longitudinal direction relative to the discharge sleeve (20) and the discharge port (22) is further closable by the closure pin. The closure pin (30) has a cylindrical portion area (30a) directed to the outside and the discharge sleeve (20) has a cylindrical portion area (20a) directed to the inside. The cylindrical portion areas (20a, 30a) form a stopping fit or a narrow loose fit and an action geometrical shape (34) for reducing a pressure and/or reducing a stream of the substance are provided on the cylindrical portion areas (20a, 30a) of the closure pin (30) and/or the discharge sleeve (20).
